This video series put things into perspective very easily. Every story has two sides, and the western narrative so easily supports treason and terrorism against the Chinese government as normal. They see the government of China as an illegitimate regime and would rather see destruction and chaos against it than stability and progress.
China’s extradition law would be normal and even lax in the grand scheme of things. Every western state has the capacity to persecute people who make themselves enemies of the state by colluding with foreign nations or other serious crimes.
We were also not told the whole story of how destructive and violent the protestors were.
